For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: a filter press for sludge treatment, comprising a squeezing bin 2 and four groups of supporting legs 1, the four groups of supporting legs 1 are fixedly connected to the four corners of the bottom of the squeezing bin 2, the left and right sides of the top of the squeezing bin 2 are fixedly connected with fixed rods 4, the inner walls of the two groups of fixed rods 4 are provided with hydraulic presses 3, the outer walls of the two groups of hydraulic presses 3 are fixedly connected to the inner walls of the fixed rods 4, the output ends of the two groups of hydraulic presses 3 pass through the squeezing bin 2, and are fixedly connected with push plates 5, the front and back sides of the squeezing bin 2 are slidably connected with screens 6, and the front and back sides of the squeezing bin 2 are fixedly connected with dustproof shells 10, and also include:

[0035] The pulling mechanism 7 includes two sets of protective shells 701. The sides of the two sets of protective shells 701 close to the extrusion chamber 2 are fixedly connected thereto. The sides of the inner walls of the two sets of protective shells 701 close to the hydraulic press 3 are fixedly connected with contact blocks 702. The tops of the two sets of contact blocks 702 are rotatably connected with clamping plates 703 through rotating shafts. By setting the clamping plates 703, the rollers 704 can be fixed in position to avoid the problem that the first spring 707 will not rebound and push the pressing plate 706 when being compressed. The inner wall of the contact block 702 is provided with rollers 704, and the two groups of rollers 704 are slidably connected to the contact block 702. The two groups of rollers 704 are fixedly connected to the side away from the hydraulic press 3 with a curved rod 705, and the two groups of curved rods 705 are fixedly connected to the side away from the contact block 702 with a pressing plate 706, and the two groups of pressing plates 706 are fixedly connected to the side close to the extrusion chamber 2 with a first spring 707, and the two groups of first springs 707 are fixedly connected to the inner wall of the contact block 702 on the side close to the extrusion chamber 2. 06 is fixedly connected to a bending rod 708 on one side away from the first spring 707, and the two sets of bending rods 708 are rotatably connected to a connecting block 709 on one side away from the contact block 702 through a rotating shaft, and the two sets of connecting blocks 709 are rotatably connected to a moving block 710 on one side away from the contact block 702 through a rotating shaft, and the two sets of moving blocks 710 are fixedly connected to the screen 6 on one side close to the extrusion chamber 2, and the two sets of bending rods 708 are rotatably connected to the connecting block 709 on one side away from the contact block 702 through a rotating shaft, and the two sets of connecting blocks The side of block 709 away from the contact block 702 is rotatably connected to a moving block 710 via a rotating shaft. The two groups of moving blocks 710 are fixedly connected to the screen 6 on the side close to the extrusion bin 2. By setting a pulling mechanism 7, the mechanism can pull the screen 6 over a distance. In this way, after the filter press completes the extrusion of the sludge, the screen 6 can be cleaned more effectively by moving the screen 6 over a distance. The pulling mechanism 7 is set to two groups and is symmetrically set with the middle of the extrusion bin 2 as the center.

[0036] The working principle of this embodiment is as follows: when the staff is ready to process the sludge, the sludge is first poured from the top of the squeezing bin 2, and the sludge is then stored in the squeezing bin 2. Next, the staff starts the hydraulic press 3, and the hydraulic press 3 will push the push plate 5 to move toward the inner wall of the squeezing bin 2, thereby squeezing the sludge. After completing one squeezing operation, the staff rotates the card plate 703, so that the card plate 703 no longer plays a restrictive role, and the roller 704 can start to roll. Since the bent rod 705 no longer restricts the pressing plate 706, the pressing plate 706 simultaneously releases the restriction on the first spring 707, and the first spring 707 begins to rebound and pushes the pressing plate 706 to move. When the pressing plate 706 moves, it will also drive the bent rod 705 to move to the side away from the squeezing bin 2, causing the bent rod 705 to drive the roller 704 to roll on the contact block 702. In addition, when the pressing plate 706 is pushed by the first spring 707, it will drive the bending rod 708 to move synchronously, so that the bending rod 708 drives the connecting block 709 to move, and the connecting block 709 will drive the moving block 710 to move when moving, and finally the moving block 710 drives the screen 6 to slide in the extrusion bin 2, so that the screen 6 moves out of the extrusion area, so as to proceed to the next step.

[0037] Example 2: Please refer to Figure 5-Figure 6 On the basis of the first embodiment, the present invention provides a technical solution: an adjusting mechanism 8, the adjusting mechanism 8 comprises two groups of arc-shaped rods 801, the two groups of arc-shaped rods 801 are fixedly connected to the dustproof shell 10 on one side thereof, the inner walls of the two groups of arc-shaped rods 801 are provided with sliding rods 804, the upper and lower ends of the two groups of sliding rods 804 are fixedly connected to the inner walls of the arc-shaped rods 801, the outer walls of the two groups of sliding rods 804 are provided with sliding blocks 803, the inner walls of the two groups of sliding blocks 803 are slidably connected to the sliding rods 804, and the tops of the two groups of sliding blocks 803 are fixedly connected with second springs 802, and the moving distance of the sliding blocks 803 can be limited by setting the second springs 802, so that the sliding blocks 803 will not exceed the limit stretching distance of the second springs 802 when moving downward, thereby protecting the rotation of the screen 6. Angle, the tops of the two groups of second springs 802 are fixedly connected to the top of the inner wall of the arc rod 801, the middle end of the sliding block 803 is slidably connected with a pulling rod 807, the side of the pulling rod 807 away from the sliding block 803 is fixedly connected with a pulling plate 808, the side of the pulling rod 807 away from the pulling plate 808 is fixedly connected with a positioning plate 805, the upper and lower ends of the positioning plate 805 are rotatably connected with a hook plate 806 through a rotating shaft, and an adjusting mechanism 8 is set, which can make the screen 6 rotate at different degrees according to the different moving distances of the sliding block 803. Since the screen 6 has different rotation angles, when processing the screen 6, the processing work can be carried out according to the different compaction states of the sludge, and the adjusting mechanism 8 is set to two groups and is symmetrically arranged with the middle of the extrusion bin 2 as the center.

[0038] The working principle of this embodiment is as follows: when the screen 6 is removed, the staff starts to pull the pulling plate 808 to move upward or downward. At this time, the movement of the pulling plate 808 will drive the pulling rod 807 to move together. During the movement of the pulling rod 807, the sliding block 803 will be driven to move in the same direction, thereby causing the sliding block 803 to slide on the sliding rod 804. When the sliding block 803 slides upward, the second spring 802 will be squeezed, causing the second spring 802 to contract; and when the sliding block 803 moves downward, the second spring 802 will be stretched. When the sliding block 803 has finished moving, the staff first pushes the pulling plate 808 to cause the pulling plate 808 to drive the pulling plate 808 to pull the second spring 802. The rod 807 moves to one side of the screen 6, allowing the pulling rod 807 to push the positioning plate 805 to contact the screen 6. Then, the staff continues to move the pulling plate 808 up and down, and drives the pulling rod 807 to move up and down through the pulling plate 808, and transmits this movement to the positioning plate 805. In this way, when the positioning plate 805 continues to move, the hook plate 806 will combine with the mesh of the screen 6. At this time, the staff pulls the pulling plate 808 to move away from the extrusion bin 2, causing the screen 6 to be pulled backward by the hook plate 806 and rotate. Moreover, due to the different contact positions between the hook plate 806 and the screen 6, the rotation direction of the screen 6 will also be different, and the sludge remaining in the mesh of the screen 6 will fall at different speeds when reaching different rotation angles.

[0039] Example 3: Please refer to Figure 7-Figure 8On the basis of the first and second embodiments, the present invention provides a technical solution: a knocking mechanism 9, the knocking mechanism 9 includes a top plate 901, the bottom of the top plate 901 is fixedly connected to the top of the extrusion bin 2, the top of the top plate 901 is fixedly connected with two sets of limit blocks 902, and the two sets of limit blocks 902 are fixedly connected with a suspension rod 903 on one side close to each other. By setting the suspension rod 903, the load-bearing block 904 can be moved to different positions with the help of the suspension rod 903, so that the local part of the screen 6 can be Precise knocking is performed to solve the problem of residual sludge on the inner wall of the area, thereby achieving precise treatment. The outer wall of the suspension rod 903 is slidably connected to a load-bearing block 904, and the bottom of the load-bearing block 904 is fixedly connected to a telescopic rod 905, and the bottom of the telescopic rod 905 is fixedly connected to a bottom plate 906. The left and right sides of the bottom plate 906 are rotatably connected to a rotating rod 910 through a rotating shaft. The left and right sides of the bottom plate 906 are fixedly connected to motors 907. The output ends of the two sets of motors 907 are rotatably connected to a swinging plate 911. The middle end of the bottom of the plate 906 is fixedly connected to a protective shell 908, and the inner wall of the protective shell 908 is fixedly connected to a third spring 909. By setting the third spring 909, the third spring 909 can push the knocking block 912 multiple times. In the process of pushing the knocking block 912 multiple times, its driving force will slowly decrease. At this time, the sludge above will stick to the sludge below when moving downward. As the knocking force gradually decreases, the screen 6 will not be easily deformed. The bottoms of the two sets of swinging plates 911 are both connected. A knocking block 912 is rotatably connected via a rotating shaft, and a clamping rod 913 is fixedly connected to the sides of the two groups of knocking blocks 912 that are close to each other. By setting the clamping rod 913, the two groups of knocking blocks 912 can perform synchronous knocking movements. A rotating block 914 is fixedly connected to the outer wall of the clamping rod 913, and a rotating rod 910 is fixedly connected to the top of the rotating block 914. The rotating rod 910 is in contact with the third spring 909. The knocking mechanism 9 is set to two groups and is symmetrically set with the middle of the extrusion bin 2 as the center.

[0040] The working principle of this embodiment is as follows: when the screen 6 is tilted, the staff adjusts the telescopic rod 905 to telescope downward or upward. Then, the motor 907 is started to work, and the rotation of the motor 907 causes the swing plate 911 to rotate in the direction of the third spring 909. During the rotation of the swing plate 911, the knocking block 912 is driven to rotate, and the rotation of the knocking block 912 drives the clamping rod 913 to move synchronously, and the movement of the clamping rod 913 drives the rotating rod 910 to move, and the rotating rod squeezes the third spring 909 during the movement, causing the third spring 909 to be compressed. At this time, if the motor 907 stops rotating, the third spring 909 will start to rebound, thereby pushing the rotating rod 910 to rotate, and the rotating rod 910 will push the rotating block 914 to rotate synchronously, and the rotating block 914 drives the clamping rod 913 to rotate, and the clamping rod 913 drives the knocking block 912 to move toward the screen 6 and knock on the screen 6. Through the knocking of the knocking block 912, the sludge on the screen 6 begins to roll down. In addition, since the third spring 909 will shake multiple times when releasing the pressure, the knocking block 912 will knock on the screen 6 multiple times, and the knocking force will gradually decrease, so that the sludge above the screen 6 is shaken out and slides down, thereby bringing out the sludge below, thereby completing the dredging work.
